Products / Parker / Seal and O-Rings / Rod Seal/Wiper Praedifa Series EN
Rod seal and wiper for pneumatic cylinders. U-cup design with front-face cover lip. Combines the functions sealing, wiping and holding in place. Robust design with extreme wear resistance.
The self-retaining Ultrathan® EN rod
seal/wiper ring for piston rods of pneumatic cylinders performs two
functions: sealing and wiping.
The Ultrathan® compound is characterized by extremely high wear
resistance.
The dirt shield formed at the wiper prevents moisture from migrating
underneath the seal into the groove. As a result, corrosion which
frequently occurs inside the groove can be avoided. In addition, due
to the absence of undercuts and dead spaces, the assembly space in
front of the seal is easy to clean. This makes the EN seal/wiper
ring particularly well suited for food and pharmaceutical production
and for all other applications requiring easy- to-clean components.
• Bi-functional element: seal and wiper.
• Robust seal profile for harshest operating conditions.
• Extreme wear resistance.
• No risk of corrosion since the combined retainer and wiper part
eliminates the need for additional wire circlips.
• Long service life due to coordinated geometries of the functional
lips and compound selection.
• Smooth running due to optimum lubricant-retaining sealing lip
geometry.
• Excellent media resistance in case of suitable compound selection.
• Suitable compounds available for special requirements of the food
processing industry.
• Identical housing for E7, E8, E9, EU, EF, EN, EW and ET.
• Installation in open housings.
• Low compression set.
• The coordinated geometries of the seal and wiper lips achieve
favorable friction coefficients and long service life.
• Product geometry prevents dirt deposits at the front face of the
cylinder.
